This company sells instructions via infomercials, and internet websites, on converting transportation vehicles to "water hybrids," that use the "atomic power of hydrogen" to boost the fuel economy. The Water4gas system runs in theory by adding a small amount of a mixed hydrogen/oxygen gas, called Brown's Gas, into the vehicle's fuel system. This enriched mixture of hydrogen, oxygen (oxyhydrogen) and gasoline is bonded together molecularly and magnetically. According to the company's advertising, the combined fuel results in better fuel economy and an increase in miles per gallon.

The Better Business Bureau warns consumers to beware of false claims from marketers of so-called fuel saving devices. Many of these products claim to improve fuel efficiency, reduce harmful emissions and reduce engine wear and tear. These devices typically attach to the engine or gas that many Web sites make unbelievable claims for various after-market automotive devices (fuel-line magnets, air bleed devices and retrofit gadgets) and oil and gasoline additives that supposedly increase gas mileage for automobiles.

Before adding any fuel-savings device to your vehicle, check with your mechanic. You may end up with a voided manufacturers warranty and serious engine problems by adding after market devices to your engine. The United States Environmental Protection Agency has evaluated over a hundred alleged gas saving devices and found that none significantly improved gas mileage. Some even damaged car engines or caused substantial increases in exhaust emissions. Consumers should be skeptical of devices when significant fuel savings are claimed, over enthusiastic testimonials are used in support of claims, claims are difficult for consumers to evaluate, or if the product is advertised with implied government approval.
